[0 all whom 2123 may concern.-

Be it known that 1, CHARLES A.

Fig. 16 is a perspective view,partly in section, of one of the gears. Fig. 17 isa sectional detail ofthe clutching devices that control the action of the binding devices onthe line 17 17 of Fig. 1.

The binder herein shown and described is especially adapted to use as aplatform binderthat is, one adapted to take the grain directly from theplatform upon which it falls without elevating.

I have shown a harvesting machine, to which the binder here shown anddescribed is especially adapted, in another application, filed June 20,1892, Serial No. 437,372.

A is the main binder-frame, of the usual U-shaped kind, having avertical standard and horizontal sleeves A and A A being for the shaft13 and A for the shaft B. Upon the shaft B is mounted theknotter-driving devices and the bundle-discharging arms.

Upon the sleeve-like portion of the main frame adjacent,to the knottingdevices an arm a is secured, upon which are mounted gears for giving thepackers and knot-ting devices movement. I have shown it as having an eyefitting closely upon the end of the sleeve, (see Fig. 10,) which I deemto be the preferable way; but it may be differently mounted. In order toprevent the arm from turning on the sleeve, I carry down from the lattera part a and bolt it to the end of the arm a. This arm (shown in fulllines in Fig. 10) can be traced by full and dotted lines in Fig. 1. Theouter end of the arm a is hollowed to receive a short bar a preferablyhollow, to which other parts are connect-ed, as shown in Fig. 18.

C is so much of the knotter-frame as necessary to illustrate my presentinvention. It is here shown only because it will aid in leading to aproper understanding of my present invention only in so far as it issupported and also forms a support for other parts. The knotting devicesare not shown because they will form the subject-matter of anotherapplication. They are loosely supported on the rear end of the shaft B,as best seen in Figs. 3 and 12. This knotter-frame must be preventedfrom rotating with the-shaft, to accomplish which and to furnish asupport for the packer-shaft I provide the arm C. In Fig. 8 it will beseen that this arm is made to surround the end of the knotter-framesleeve, and Fig.1 shows that the said arm has its eye out out and lugsprovided whereby it maybe turned tightly onto the sleeve of theknotterframe by the bolt 0. At its outer end it is provided with thehollow c, in which rests the bar a The said bar is held in the hollow 0in the recess of the outer end of the arm a and in a correspondinghollow in the outer end of the arm 0 by means of the yokebolts 0 and cDownreaching from the main portion of the arm C is the arm C To this andto the knotte r-frame C is secured the breast-plate C IOC 4o arm a.

having the usual slot, and flanges through and between which the needlepasses. Figs. 1 and 12.) I

The gearing-supporting arm a is provided (See with an eye 0?, that issplit and provided with lugs, so as to be pinched bya bolt. (Shown indotted lines in Fig. 10.) cured to the main frame and rigidlyconnectedto the'bar a and being,besides, connected rig- IO idly to theknotter-frame C and the arm 0' a frame in the form of a parallelogram isshown, to which I secure and withinwhich parallelogram-like frame Iplacemy packers and the devices for clutching and unclutchr5 ing the bindingdevices proper and for giv ing them and the packersmovement.

Inorder to keep the knotter-frame O, and hence the arm C, from movingrearward, so as to let the parts of the frame spread apart,

I providea collar C having a set-screw by which it is held firmly totheshaft. The discharge-arm C is foreonvenience secured to this collar.I

The prime mover of all of the parts of the binder is a shaft D,preferably square. (Shown This shaft is journaledat one end in Fig. 3;)in any convenient portion of the harvesterframe, no part of which isshown, it being sufficient for the purpose of this application to 0 saythat either the journal-bearing upon the said harvester-frame may besuch as to provide a slight pivotal movement by a globebox or otherwell-known means, or the said shaft may itself be provided with auniversal .35 joint.

5 a square eye into which the shaftD is inserted, and having its hub delongated. This shaft rotates continuously in the direction indicated bythe arrow in Fig. 1. To it, by means of clutching devices soon to be de-5 o scribed, is connected the packers and the binding devices proper.The means whereby the latter are actuated will now be considered. Themain binder-gear E is keyed to the shaft B. Projecting from the arm a isthe stud E is another intermediate gear, that for the present moment maybe considered as supported upon any suitable axis. The two intermediategears mesh into each other and into the pinion d and the'gear E, bywhich means the latter is moved in the direction indicated by the curvedarrow in Fig. 1. The knotting devices are located upon the knotter-frameso as to be operated and controlled by the (5 wheel E, and the latterbeing keyed to the shaft B, that has the crank B and the needle-shaftB',-having the crank B and the This arm firmly se-- pitmanB". connectingthem, the needle receives its oscillations by the rotation of the, I I Isaid wheel. I l 'As'th is binder is intended to automatically determinethe proper size of the gavels to be bound, a clutching device isprovided whereby the'binding devices may be held in position during theaccumulation thereof. The lever 01 terminates in the" hook d. Pivoted tothe'side of the wheel E is thepawl e, havingthe arm 6, adaptedto engagethe hook d" of the lever d as seen in Fig. 1. The pawl is controlled bya spring e ,"one endof which is secured to the said pawl and the othertoa lug on the wheel E; The two positions of the pawl are shown in Fig.2, that infull lines I I being the position to which it is thrown by thespring to produce engagement of the wheel E with that of E". Upon thewheel Eare two projections e and 6 Their location, as shown in Fig. 2,is such that as the pawl is set free and forced to the position shown infull will strike upon the end E is mutilated by omission of three teeth;

\rVhen the parts are inthe position shown in that figure, the gear Ewill run idle, having no influence whatever upon the wheel E; but

if the lever d be moved so that its hook (2" wheel E to rotate for alittle distance, and the teeth of the wheel E will engage those of thewheel E, and the latter will be rotated until the gear E reaches themutilated portion of the wheel E. As the said wheel revolves, it carrieswith it the pawl e, which is held by the spring e in the position shownin full lines in Fig. 2. At the time the needle takes the stress of thegavel off the packers the spring (1 asserts itself to raise the lever dinto the position shown in dotted lines when the hook d lies in theorbit of the arm e of the pawl. The said arm e will engage the hook d ata time just previous to the end of the revolution of the Wheel E, andduring the remainder of the revolution the hook d will hold the arm 6'until the said arm assumes the position shown in dotted lines in Fig. 2,the holding of which arm forces the pawl out of engagement with theprojection c on the wheel E. With the parts in a state of rest and thespring 6 under compression, as shown by dotted lines in Fig. 2, thestress of the latter would tend to start the wheel E backward. Toprevent this a notch e is provided in the wheel E, and a spring-bolt 6having an anti- -friction-roller is adapted to be forced therein.

This bolt performs other offices that will soon be explained.

The means whereby the increasing gavel is instrumental in tripping theclutching devices will be understood by reference to Fig. 2, where thelever d is shown in dott d lines will draw away from the end 6' of thepawl e a the said pawl will be thrown by its spring to the positionshown in Fig. 2, when the'projec" tion e3"will engage the pawl and forcethe IOO ' in its positionwhile the binding devices proper are held fromaction and in full lines as having moved to permit the clutching devicesof the binding mechanism to become engaged. Let it be assumed, for themoment, that the packer-cranks are being turned positively by thegear-wheel E Then let it be assumed that they have been rotated untilthe receptacle formed by the breast-plate, the binding-table, thetripping-compressor, and the packer, as shown in Fig. 2, has becomefilled. The packer can no longer compress the gavel. The gear E beingheld from rotation, the pinion d can no longer turn it, but with thesaid gear so held the pinion will exert itself to roll along theperiphery of the gear and carry upward with it that end of the lever (1which movement will carry the end of the lever having the hook ddownward and throw it from engagement with the arm .2 of the pawl 9 andthe latter will be set free to assume the position shown in full linesin Fig. 2. As long as a sufficient amount of resistance to the movementof the packer is retained, the lever d will be held in the positionshown in full lines in Fig. 2, but the moment the pressure is releasedthe lever will be drawn upward by the spring-rod (1 This rod passesthrough a hole in the flange of the part a, above which is the spring dand the nut d The spring may be adjusted by turning the nut al so as tohold it in any degree of tension while the binding devices are inposition of rest.

The movement of the point of the packers -is shown by dotted lines inFig. 1, and the path traversed by the point of the needle is also thereshown in dotted lines. From these lines it will be seen that the packerreaches into the grain some distance beyond the path of the needle. Inorder to avoid choking while the needle is up, I provide clutchingdevices, whereby the packers are thrown out of action while the bindingdevices proper are doing their work.

Reference to Fig. 14 will show that the gear E revolves on a sleeve,which sleeve is one of the journals F of the packer-shaft. This journalis hollowed out to receive the spring f and upon the face of the crank Fis cored out the recessf, and connecting this recess and the hollow forthe spring is the'eyef'. Into the hollow, the eye, and the recess isplaced the sliding boltf for construction of which see Fig. 9. Upon thebolt is placed the collarf Against this and against the end of thehollow journal the spring rests, the result being that the sliding boltfis normally held inclosed within the recessfot' the packercrank.

Refercnce to Fig. 16 will show the gear E to have enlargements e of itshub, and in these, upon opposite sides, recesses e". Into these the hubof the sliding bolt may draw, as shown in Figs. 2, 3, and 4. Turningparticularly to Fig. 4 it will be seen that the cross-head f of thesliding bolt lies within the recess f of the crank, but notin therecesses e of the gear E Clearly, then, the gear E may rotate upon thesleeve-like journal F of the packer-shaft without turning the latter.

In Figs. 3 and 4 a lever H is shown pivoted to a lug a of the frame A.This bar at its end it rests upon the sliding bolt c and at its end Itrests upon the cross-head slide-bolt f preferably having an eye in itsend adapted to pass onto the extreme end of the said bolt.

In Fig. 3 it will be seen that the antifriction-roller at the end of thesliding bolt (2 rests within the notch e, the spring of the sliding bolte having forced it there. The pressure upon the end it of the lever Hhaving been released, the spring f will exert it self to force thesliding boltf to the position shown in Fig. 3, where it will be seenthat the cross-head f lies within the slot f of the packer-crank F andthe recesses e of the gear E In consequence of this the packers will berotated. When the gear E is in the position shown in Fig. 3, the teethof the gear E move freely within the recess thereof, and the gear E,being in the position there shown during all of the time of theformation of a gavel, the parts retain the position seen in that figure;but the packers having finally met with resistance in thegavel-receptacle the lever d is forced in the direction to trip theclutching devices that put the binding mechanism proper into movement.The instant the wheel E is turned the roller of the sliding bolt 6 isforced eudwise and the crosshead f forced out of the recesses e in thegear E and the packers are permitted to stop. (See Fig. 4.)

The bundle-compressing devices are best shown in Fig. 1 and made clearby various detail figures. Upon the needle-shaft B is placed the needleG, which is provided with the arm 9. I is the resistant, in the presentexemplification of the invention, also a compressor. Pivoted to a lug bon the main frame is the arm I, having the lug This part I will bedesignated hereinafter as the tripping-compressor. The arm g and thetripping-compressor are side by side and so close that the arm g maystrike beneath the lug 't' and lift the said tripping-compressor toposition for receiving the gavel, as shown in Figs. 1 and 12. While theneedle is in this position it holds the tripping-compressor erect, butWhile it is passing upward and perfprming its office of carrying thetwine up to the knotting device and serves as one element of thecompressing devices it cannot so hold the compressor. Thetripping-compressor I must be held, and in order to yield in compressingmust be sustained elastically.

In Fig. 1 is shown an arm 2', terminating in an antifriction-rollerd.Ishall treat this roller in my claims as but merely an antifriction partof the arm '5.

J is a bolt, against the head of which the extremity of the arm 11rests, the bolt being held in position by the spring j. In consid- IIOering this matter it must be supposed that the needle has passed upward,so that the arm g no longer rests on the lug i. It will be seen that ifthe tripping-compressor I be forced outward by the bundle the springjwill yield; but it is necessary to get the spring-bolt J out of the wayto permit the tripping-compressor to fall to allow the passage of thebundle.

Adjacent to the hub of the needle is the escapement g.

K is a latch (shown in detail in Fig. '7) having the pivot 7c. Thelatter enters the eye in the main frame. It has the shoulder k adaptedto be engaged by the escapement g on the needle-hub. It is provided withan eye 70''. Through this eye the spring-bolt J passes, and the spring jrests against the end 10 It will be seen, then, that the spring tends tomove the latch K so as to force the shoulder 7r under the escapement gwhen permitted to do so. The sliding bolt J is held in place by a sleeveL, having the trunnion Z, the latter forming a pivot that passes intothe eye l of the main frame. (See Fig. 6.) Through this sleeve the boltJ extends, where it is threaded to receive the nutj. The eye k is large,so that the bolt J passes loosely therethrough and the sleeve L ispointed at Z and the lower extremity of the latch adjacent to the eye isprovided with an angular projection. By means of this angularprojection, and that of t the lower extremity of the latch may rock onthe bolt J. Assuming that the needle is passing upward to do its work incarrying the band, the latch will spring away and permit the escapementg to move upward. The action of the springj will have the effect offorcing the shoulder 70 toward the needleshaft, and after the needle hasdone its work and has started backward the escapement will come incontact with the shoulder and force the whole down, carrying with it thespring-bolt J, rocking it on the pivot of its support Z. This will throwthe head of the bolt from the position shown in Fig. 1 to that shown inFig. 5, where the arm 7 is seen to have passed off from it. As the latchK can only rock on its pivot 70, it is soon forced down so far that itswings out of contact with the escapement which in Fig. 5 it is seenpass ing. .As soon as the needle approaches its lowermost position thearm g comes in contact with the lugt' and forces the trippingcompressorto its home position. The packers are carried on their cranks in theusual manner, and the heel ends of the same are controlled by the linksM and M, pivoted to the knotter-frame.

It is seen that- I have two clutching devices, one for putting thebinding devices proper into motion and stopping them and another forputting the packers into motion and stop ping themthat is to say,through a train of mechanism the packers are compelled to throwthemselves out of action, and I shall claim my pivoted lever that iscaused to move by the holding of the driving-pinion from rotation andits consequent movement around the periphery of the driven gear becauseof the resistance afforded for the packers as means for permitting thepackers to be thrown out of engagement, as well as permitting thebinding devices to be thrown into operation.
